I believe they are hard back. I was browsing book depository last night and it came up for pre order. I checked out the publishers website, and they have pre order. No description other than Hardback. It would be nice if they were some kind of matching special edition. If for nothing else than as a nice matching set on the book case.

Just an FYI, I asked Brian James Freeman on thedarktower.org about this, and it sounds like they have already shipped. He is looking into my order. If you haven't done so already, I would contact them.
